@wat @twine ELIE MONEUSE AND LOUIS DUPARQUET, OF NEW YORK, N. Y.

Letters Patent No. 95,599, dated October 5, 1869.

The Schedule x'et'erx'eci.l to in these Letters Patent and making part of. the same.

To all whom it may concern -Be it known that we, ELIE MoNEUsn and LOUIS DUPARQU'ET, of the oityand State lof New York; have invented and made anew and useful Improvement in Coffee-Pots; and we do hereby declare the following to be,a full, clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, wherein- Figure 4 is an elevation of the codec-pot, with a portion of the case broken open and Figure 2 is a section of the coffee-holder detached.

Similar letters denote the same parts.

Coffee-pots have before been made with strainers for holdingr the coffee, sotliat the hot water will lbe poured through the same, but these are not adapted to the lowering of the strainer into the coee liquid, if there is bnta'small quantity of' said liquid.

Bags and floating celibe-holders have also been used, but they do not -force the hot water to pass through the mass of ground coilee4 as the former is poured intothe cotlee-pot.

Our invention consists' in a movable foraminous coee-holdiug piston, fitting the interior ofthe coecpot sufficiently tight to cause the hot water to pass 'through the piston and the coi'ee that it contains.

This codec-holding piston 'can be placed at any desired point in'the coffee-pot, so that the coffee can always remain in the liquid, or it may be drawn up or down to suit the circumstances.

If the coffee-holding pistou remained in the liquid, 'the colee might become thick. It' the piston is removed aud hot water introduced, the pistou and coffee can then be lowered into the same. The entire coffee grounds can be removed with promptness or they can be suspended labovethe liquid coiee in said vessel, if desired, thus greatly facilitating the production of thev best quality of coli'ee.

In the drawinga represents the base of the coffee-pot;

b, the cylinder, with a bottom, forming the receptacle for the liquid cotl'ee 5 l c is a. sediment cock, for drawing off the thicker or second quality coli'ee; and

(l is a cock, some little higher up, for drawing oft' the liquid coffee.

At the top of' the coffee-pot is aange, for receiving water in the annular trough around the coffeeholder l, and e is the cover with the interior flange f andfexterior ilange t', to set around the top of the 'vessel b, and retain any vapors and aroma, and return them to the coffee as they condense on the under side of the cover e. A

The valve h'adlnits air as the coffee runs out.

In the side of the vessel b a thermometer is introduced, as at k, to denote the temperature ofthe contents, and a glass tube,'1, fis also employed, the same communicating at thev bottom into the vessel b, and

at the side of the'glassjtube numbers are stamped' upon the vessel b, to denote the number of gallons.

pint-s, or other measures of' liquid coffee there may be in the coffee-pot'. y

The glass tube maybe open at its upper end to allow it to be cleaned.

The movable i'oraminons coffee-holding piston is formed with the bottom n, sides o, and lids p, that are hinged, so as to be lifted in introducing or removing the ground coli'ee.

The edges of this piston tit the interior of the coffee-pot sufiioiently to prevent much water passing between the piston and the 'cylinder b, and cause the saine to pass through the perforations of the piston, and thereby extract from the ground coffee its propcrt-ics.

The baill or handle r allows the piston to he lifted up or lowered down as desired.

What we claim, and desire to Secure by Letters Patent, is- A 1. The movable bralninous coffee-holding' piston, formed with the bottom n, lids 'p, sides o, and pro-- vided with a handle, in combination with the cotfeeholding cylinder b, into which said piston tits, as and for the purposes set forth.

2. The thermometer' k, glass-tube Z, and divisions applied to and combined with the coffee-holding cylinderb, in the manner and for the purposes set forth.

In witness whereof, we have hereunto set our signatures, this 22d day of J une, A. D, 1869.

ELIE MONEUSE. LOUIS DUPARQUET.
